axial bore 10 pzmvded in a sore the stein-extension 3 in the eseeinblinnl of the valve .ln this form of the device, the entire coro carrying the valve parte enters the upper e'nd of the valve stein and tits `flush with the upper end of the stem, so that its valve operating rod or plunger is readily accessible for operating the valve.

Normally, as in standard tire-valve, a suitable enternally threaded cap 15 is threaded upon stein-extension 3 to protect the core ai. end its associated parte, and also a suitable internally tln'eaded hood 1G seated lupon stein 'l to inclos'e und protect the sternezttension 2:3 :and its cap l5.

The slightly modified-form oi niy valve shown in Fig: Llis :adapted more especially for employment Where a larger `volume oil' entering air than is allowed by the preferred forni of the valve shownin Fig. 1 is desired. 'In this modified form of the valve,v

the core d', instead of titting Within, and

consequently limiting the passage of air through the stein, is enlarged and formed lengthwise with an extension l?, which is longitudinally recessed to. provide the sphere-chamber 5 and rodheed chamber 7', but also counter-bored end threaded to provide an internally threaded socket, at l8 adapted for engagement with the cnternnl threads tc the stem-extension 3p whereby the core 4' is adapted to lit upon the stem shown, a gasket l2 being; pieterzthly interposed between the upper end ot the stein-en ension 3 and the shoulders 20 formed in the core-extension l? by pri'fviding the counter-bored socket 1S. In this form of valve, the cap l5, while not shown,

is 'adapted to seat upon the upper externally v threaded portion of 'the core Citherivlse than stated, this form of the valve is substantially-similar to the preferred torni oit valve beforedescribed, the core Ua although larger in sizevfthan the core et and consev quently providing or a'oi'ding a larger sphere-chamber with a eorrespondinoly larger valve-closing sphere, being equally adapted for convenient attachment to, end use with, stendard stems now' generally in use.

In use or operation, the sphere 6 will lee tightly held to its seat lin yveiveclosing position under the substantially constant outward pressure' of the compressed air or other fluid contained Within the tube other vessel 2. Should the tube or other vessel 2 become punctured or otherwise deflated, the sphere 6 Will automatic. l y* unseat itself and be supported by the disk l2,

which disk will likewise-support the sphere 6 during the iniation or illing oi the tube or other vessel 2, et which time the greater pressure of the :incoming air will toi-ce the sphere 6 from its seat. The"sphere 6 may' also be unseated when desired, as during inmensen lation of the vessel 2 or es inascertaining l the pressure of the containedair er' other duid, by downwardly nienipulatinp; the rod or plunger 9, the under face of the head' 8 of which may be either dat, as seen in Figs. 4:

K and 5, or concaved, as seen in Figs. l and 2,

its attached valve parts are readily attachahle and detachable from the standard valve stein in their assembled condition.

--lily new valve may be 4cheaply produced, muy be readily attached to, and used with, standard valve stems Without change in 'their construction, and has been found eX- ceedingly etlieient in operation.

l't is to be understood that minor changes in the toi-rn, construction, arrangement, and combi.nadieny of the several parts of the valve may he niade and substituted for those he `Min shown and described Without departing;5 ',roin the nature and principle of my invention.

Having thus described my invention, what l claim and desire to secure by Letters lhitent is:

l. ln en inflation valve, the combinetion'with :i standard valve stein adapted to be perinenidly fitted at its lower end to an erticle to be inflated and having its upper ond soretti-threaded, of e self-contained vulve comprising n core having an enlarged r in its lower end terminating in a curved velve seat, and a reduced bore eX- tendinpj :troni seid recess to the upper end oit sei-d core, and e rounded countersink at the lower end of said reduced bore aiorda recess or seat above the valve seat in said enlarged recess7 en independent valveoperating rod or plunger adapted to be fitted in the reduced bore in said core through said enlarged recess and provided With acurved heed adapted to entirely enter the countersink of said bore end engage the rounded seat therein, a ball valve loosely fitted inthe enlarged recess in said core and adapted to engage the seat thereln, a perztoragted disk iloserevrthreaded into the lower, end of said enlarged recess in seid core' to maintain the parts of' the valve in'assembled condition, the seid headed valve-operating rod and its seat serving as an auxiliary valve to check the flow of any pressure escaping past the bell valve when in pressure closed condition, and said core with its assembled or self-contained valve parte adapted to be screwed 'article to be inflated and havinfT an exteriorly threaded reduced portion at its upper end adapted to receive a closing cap, the said reduced portion also being interiorly screwthreaded to a depth substantially equal- 'to the depth of said reduced portion of a selfcontained assembled valve structure adapted to be bodily fitted in and removed from the upper end of said fixed standard valve stem` and comprising an exteriorly threaded core of uniform diameter throughout its entire length and of substantially the same depth as .the interiorly threaded reduced portion or" said stem'and provided in its inner end with an enlarged recess terminating in a curved valve seat, a bore of smaller diameter extending from said recess to the outer end ot said core, and a countersink or chamber at vthe innerl end of said smaller bore, the `said enlarged recess being screwthreaded at its loiver end, an independent headed. valveoperating rod adapted to be fitted in the lower end ot said coreand' extending through the reduced bore therein With-its head fitting:r in the coiintersink of said bore and its upper end adapted to be projected beyond the upper end of the core. by the pressure of the valve', a ball valve loosely fitted in the enlarged recess in said. core and adapted to engage the curved seat therein under pressure, and a perforated disk i threaded Wholly within the lower end of said recess to maintain the parts of the valve in assembled condition in said eore,. whereby the said valve in itsvassenibled condition may readily be litted in and removed .from the standard valve stern. 4

In an inflation valve, the combination with a standard valve stem adapted Ato he permanently secured to the article to be inilated andhaving an exteriorly threaded reduced portion at its upper end adapted to receive a closing cap, the said reduced portion also being interiorly screivthreaded to a depth substantially equal to the depth of said reduced portion, of a self-contained assembled val te structure adapted to be bodily 'fitted in and removed from the upper end of the standard valve stem, and comprising an exteriorly threaded core of uniform diameter throughout its entire length and of substantially the same -depth as the interiorly threaded reduced portion of said stem and provided in its inner end With an enlarged recess terminating in a curved valve seat, a bore of smallerdiani'eter .extending from said recess to the outer end of said core, and a countersink or chamber at' the inner end of said smaller bore, the isaid enlarged recess being screivthreaded at its lower end, an independent headed valve-operating rod adapted to be fitted in the.lo\ver end of said core and ex tending through the reduced bore therein with its head fitting in the countersink of said bore andits upper end adapted to be projected beyond the upper end of the core by the pressure of the valve, f a ball valve loosely fitted in the enlarged recess in' said core and adapted to engage the curved seat therein under pressure, and a perforated, disk threaded Wholly within the lower end of said recess to maintain the parts of the 4 be fitted in and removed from the standard valvev stem.

In testimony whereof, l have signed my name to this specification.
